2017-04-26 65548-615 TE525MM Installed Precipitation Installed on the top southeast corner of the scaffolding at the Bouldin Corn site with the initial set up of the tower.
2018-10-18 65548-615 TE525MM Calibration Precipitation Got 94 of 100 tips. Adjusted a total of 1 turn CW. 2018-10-18: Got 94 of 100 tips - adjusted screws 0.5 turns CW 2018-10-25: Got 97 tips and adjusted set screws 0.5 turn CW. 2018-11-01: 99 of 100 tips - no adjustment.
2019-10-22 65548-615 TE525MM Calibration Precipitation After cleaning the tipping bucket we connected it to a CR23x and dripped 475ml of water through the bucket which should result in 100tips. We got 99 tips – no adjustment needed.
2019-12-02 65548-615 TE525MM Removed Precipitation Removed from Bouldin Corn site and brought back to the lab after the tower fell down during a rain/wind storm on 2019-11-26.
2019-12-13 65548-615 TE525MM Installed Precipitation Re-installed at Bouldin Corn after re-assembling tower.
2019-12-13 65548-615 TE525MM Tested Precipitation Plugged tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket which should result in 100 tips. Got 102 tips and did not adjust the bucket.
2020-11-19 65548-615 TE525MM Precipitation Plugged tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket which should result in 100 tips. Got 116 tips. Did not adjust - will retest with better water metering system.
2020-12-03 65548-615 TE525MM Tested Precipitation Plugged tipping bucket into the calibration CR23x and dripped 475ml of water through the bucket (1/2 of the bottle at a time) which should result in 100 tips. Got 117 tips. Did not adjust - will retest with better water metering system.
2021-10-21 65548-615 TE525MM Tested Precipitation We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes. We got 54 tips and adjusted its set screws 1.5 turns CCW (1/2 turn of both screws is a 2-3% adjustment).
2021-11-05 65548-615 TE525MM Tested Precipitation We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes. We got 52 tips but forgot to adjust the screws.
2021-11-18 65548-615 TE525MM Calibration Precipitation I adjusted the screw 1 turn CCW before testing b/c I forgot to adjust it after the previous test. We dripped 240ml of water through the bucket using a peristaltic pump powered with a lithium battery. This should result in 50 tips in about 20 minutes.
